Answer:B. A customer gets sick with E. Coli after eating lettuce that was cut on same cutting board as raw meat.

Explanation:

The glass is not a food and is not considered cross contamination.

The meat was fully cooked and the E. Coli is destroyed.

the same situation as A.

Answer: Option B

Explanation:

The cross contamination can be defined as contamination which is caused due to the contamination of the other food kept aside this food.

A customer who eat lettuce gets disease by the E.coli bacteria due to cross contamination, this is because the lettuce was cut on the same board where previously raw meat was cut.

Raw meat contains E.coli which gets transmitted to the lettuce and then it was contaminated by raw meat.

Answer:

In biology, the relationship in which one organism lives inside another is described by the term endosymbiosis.

Explanation:

Endosymbiosis refers to a form of association that organisms have, in which one individual lives and performs his functions within another's body -using his resources to survive-  being  called the first symbiont, and the second host.

An example of endosymbiosis is found in bacteria that are part of the intestine of some living organisms, contributing to the process of food degradation.

Additionally, endosymbiosis is relevant in explaining the origin of eukaryotic cells from symbiosis between prokaryotic cells, which is known as endosymbiotic theory.

Water is found throughout the earth. It is comprised of hydrogen and oxygen atoms. Water changes into different physical states
madam [21]

Answer:

Water obeys the Law of Conservation of Matter despite changing into different forms because when water does change forms, the amount of water stays the same. The Law of Conservation of Matter states that before matter undergoes change, be it through physical or chemical means, the same amount of matter exists. Matter cannot be created nor destroyed during the change. When water changes from a liquid to a gas the molecules change form by breaking the bonds that held them in a liquid state, but this does not create new matter. The molecules can now move more freely but are still the same as they were before. Same goes with the change from a liquid to a solid. The molecules slow down and become more compact, forming a solid. Though again, this does not create new matter nor destroy existing matter, therefore obeying the Law of Conservation of Matter.

What would be the functional problems that would be experienced by a person in which the fiber tracts listed below have been cut
Ad libitum [116K]

1. Dorsal column-medial lemniscal pathways - It would prevent the body from receiving stimuli related to pain and temperature: Corresponds to sensory pathways related to an organism's proprioceptive awareness. It is through these pathways that sensory stimuli and electrical impulses are transmitted from the body to the brain resulting in the display of quick and efficient responses. If cut, the individual would not be successful in receiving stimuli related to pain and temperature.

2. Anterolateral pathways - It would also prevent the sensation of pain and temperature, in addition to hindering the perception of touch and pressure: Located in the anterior part of the lateral column, this pathway is responsible for the transmission of nociceptive information, generally related to pain awareness. and temperature. Its cut would not only make it difficult to transmit these factors, but it would also make it difficult to transmit extroceptive information to the cortex.

3. Spinocerebellar pathways - would hinder information about the position of body members and joints: This pathway is located between the spinal cord and the ipsilaterally in the cerebellum. It consists of thousands of axonal fibers whose main function is to transmit information about the location of the body members, arms and legs, in addition to their joints. Its cut would make it difficult, or even prevent this information from being captured by the brain.

4. Pyramidal pathways - It would prevent the union of the cerebral cortex to the motor neurons of the spinal cord: It is formed by several axons that extend between the cerebral cortex and the spinal cord passing motor information that would be interrupted if the path was cut.
